I noticed a discrepancy between the CGS34 schematic (VER 1.2) and the PCB layout pictured on the CGS website (pcb_cgs34_1-2_asr.gif) and am wondering which is correct....

Looking at the upper left hand corner of the schematic (clock input) it shows the output of the TL071 (pin 6) connected to the anode of a signal diode. The cathode of that diode connects to the CLK pin 1 of the 4024 and to one side of a 100K resistor, the other end of which goes to ground. When I follow what's going on with the PCB that resistor is in between another 100K resistor and the 100n decoupling cap for the 4024... all three components sitting between the TL071 and the 4024. That resistor is shown on the PCB as 10K, not 100K. I didn't see any notes on the CGS website about this and am wondering if it's been mentioned elsewhere... I confess I haven't read through all the CGS34/ASR threads here on the forum, so it may well have been dealt with already. However, assuming it hasn't, I repeat my original question... which is the correct value, the 100K one on the schematic or the 10K one on the PCB? Anyone???
